Hi Sofiane,


Thanks for sharing your sample image. I have converted image to PDF using new DOM approach and noticed that it creates a PDF of 507 KB. However if you to reduce PDF file size further then you can decrease the image quality using OptimizeResources() method. Please check following code snippet for reference. Hopefully it will help you to accomplish the task.

// Instantiate Document Object<o:p></o:p>

Document doc = new Document();

// Add a page to pages collection of document

Aspose.Pdf.Page page = doc.Pages.Add();

// Create an image object

Aspose.Pdf.Image image1 = new Aspose.Pdf.Image();

// Add the image into paragraphs collection of the section

page.Paragraphs.Add(image1);

// Set the image file stream

image1.File = myDir + "40Nda733a45pvN92.jpg";

doc.ProcessParagraphs();

// Optimzie the file size by removing unused objects

doc.OptimizeResources(new Document.OptimizationOptions()

{

LinkDuplcateStreams = true,

RemoveUnusedObjects = true,

RemoveUnusedStreams = true,

CompressImages = true,

ImageQuality = 80

});

// Save resultant PDF file

doc.Save(myDir+"Image2PDF_DOM.pdf");
